In an interview with NME, Radcliffe cleared up a misconception that he spent time between takes masturbating, a rumor that stemmed from a Playboy Q&A segment published in October.

"I didn’t say I wanked on set!" he insisted. "It’s frustrating when you tell a story and say, ‘Yes, I wanked a lot when I was a teenager,’ but clearly I didn’t mean on set...Can you make this clear for me: I was not wanking during the filming of Potter—I managed to restrain myself until I got home.”

So that you have the necessary information for your records, here is what Radcliffe told Playboy:

"I think I started very early—before my teens. But not when I was on set..It would have been embarrassing to walk back on set and look the dignitaries of British acting royalty in the eye, knowing what I’d been doing."
